Answer:

Answer A, 4x^2-2x-10

Step-by-step explanation:

Since we are subtracting the first listed equation from the second, we have to switch the order of those two. The second row will all become negative (just the second, not the first) since this is subtraction. You add the numbers from there and remember to keep your coefficients and variables in line (x^2 to x^2, x to x, etc.)

The volume of a gas in a container varies inversely with the pressure on the gas. If a gas has a volume of 180 cubic inches unde

fiasKO [112]

Answer:

100cubic inches

Step-by-step explanation:

varies inversely

pv = k

Find the constant of variation:

volume of 180 cubic inches under a pressure of 5 pounds

5 * 180 = k

k = 900

volume if the pressure is increased to 9 pounds per square inch?

9v = 900

divide both sides by 9

v = 100

Identify the vertex of the quadratic function in standard form y=2x^2 -16x+31

lapo4ka [179]

Answer:

(4,1)

Step-by-step explanation:

The vertex of the quadratic can be found using -b/2a. The vertex is the point (-b/2a, f(-b/2a)).

To find the x coordinate of the quadratic, define its a,b, and c. The quadratic has a = 2, b=-16, and c=31. Then -b/2a is -(-16)/2(2) = 16/4 = 4.

To find the y-coordinate, input the x=4 and solve for y.

$y=2(4)^2-16(4)+31\\y=2(16)-64+31\\y=32-64+31\\y=1$

The vertex is (4,1).
